Genes affected

CDKN2AIP (HGNC:24325): (CDKN2A interacting protein) The protein encoded by this gene regulates the DNA damage response through several different signaling pathways. One such pathway is the p53-HDM2-p21(WAF1) pathway, which is critical to the DNA damage response. Two transcript variants encoding different isoforms have been found for this gene.

The c.784T>A (p.S262T) alteration is located in exon 3 (coding exon 3) of the CDKN2AIP gene. This alteration results from a T to A substitution at nucleotide position 784, causing the serine (S) at amino acid position 262 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
